 The value is a <​prop-encoded-array>,​ composed of an arbitrary number of pairs of address and length, <address length>. The number of <u32> cells required to specify the address and length are bus-specific and are specified by the #​address-cells and #size-cells properties in the parent of the device node. If the parent node specifies a value of 0 for #​size-cells,​ the length field in the value of reg shall be omitted. The value is a <​prop-encoded-array>,​ composed of an arbitrary number of pairs of address and length, <address length>.
